10K Training: 10 Zone 3/Tempo Sessions
Summary
Zone 3 training builds sustainable speed and controlled effort — exactly what 10K racing demands. These sessions help you manage rising intensity, hold form across distance, and stay efficient deep into the race. If you want to run strong, not just fast, Zone 3 is where you start building. Zone 3 is the foundation for smart 10K performance. It’s not about speed spikes or race-day heroics — it’s about applying steady pressure and staying composed as fatigue builds. For 10K runners, this means finding rhythm early, holding posture and control through the middle, and keeping just below the redline. These tempo sessions build your aerobic engine, mental focus, and ability to sustain race effort with calm, steady execution.
What Is Zone 3 / Tempo Training?
Zone 3 sits between easy running and full threshold. It’s typically 80–87% of your maximum heart rate, and feels like 6–7 out of 10 on the RPE scale. Breathing is deeper, talking becomes limited, and form requires conscious effort to maintain. It’s controlled discomfort — strong enough to require focus, but stable enough to hold for extended periods. In this zone, you’re building aerobic strength, developing rhythm, and learning to stay efficient under increasing load. For the 10K, it’s your endurance gear — where pacing, posture, and pressure come together.
Why These Sessions Work
Zone 3 training strengthens your ability to hold effort over time — which is essential for the middle kilometers of a 10K. These sessions improve aerobic efficiency, muscular endurance, and mental pacing. They prepare you to run fast without burning out, and to stay sharp when others start to fade. They also form the bridge between easy running and threshold work, helping you progress toward race intensity in a sustainable way.

FAQ
How do I know I’m in Zone 3?
You’re breathing steadily but strongly. Talking in full sentences is out. You feel like you’re applying constant pressure, but you’re not close to maxing out.
How long should I stay in Zone 3 per session?
Tempo work typically totals 20–40 minutes of Zone 3 effort per workout, either sustained or broken into intervals.
How do I calculate my Zone 3 heart rate?

Final Thoughts
Zone 3 is your control zone. These workouts sharpen your ability to stay composed when effort builds and help you run smarter across longer race distances. For the 10K, tempo training bridges the gap between easy running and full-on racing — giving you the strength, rhythm, and pacing discipline to perform with confidence.
